You sound like you are doing the right things so I wouldn't worry if the scale doesn't reward you all the time give it some time and I'm sure you will break through your plateau.
Are you still excited by what you are doing, if not mix things up. Try new recipes, add some more fiber to your diet.
I would suggest mixing things up a bit if you've settled into a rut at the gym. I don't know what you do now, but I would think if you are just casually doing cardio perhaps work in some more strength training or do some other physical activity that you haven't tried before.
